摘    要:合成了一系列具有高热稳定性的金属有机骨架材料RE(BTC)(H2O),(RE=Y,Tb,Eu,Yx-Tb1-x,Yx-Eu1-x),除去端基水分子后可得到具有一维孔道的空旷结构RE(BTC)。其中,Y(BTC)具有良好的氢气以及甲烷储存性能。在77 K,1 atm条件下,氢气的吸附量高达1.73wt%;在室温,4 MPa条件下,Y(BTC)的甲烷储存量达到饱和,可以达到97.7 cm3.g-1(STP),在美国能源部规定的安全储运压力(3.5 MPa)下,甲烷储存量也能达到96.0 cm3.g-1(STP),与其它同类多孔材料相比具有一定的优越性。骨架中掺杂了微量金属铽(Tb),铕(Eu)的Tbx-Y1-x(BTC)(H2O),Euy-Y1-y(BTC)(H2O)与单一金属的Tb(BTC)(H2O)和Eu(BTC)(H2O)相比,不但降低了材料的成本,而且减小了浓度淬灭对材料荧光性质的影响,优化了材料的荧光性能。

关 键 词:金属有机骨架材料  稀土  储氢  甲烷储存  荧光

Abstract:A series of rare earth metal-organic framework materials RE(BTC)(H2O), RE=Y, Tb, Eu, Yx-Tb1-x, Yx-Eu1-x] with high thermal stability have been synthesized. The frameworks RE(BTC)] contain 1-dimensional channels upon removal of the terminal water molecules. Therein, Y(BTC) expresses an excellent storage ability of H2 and CH4. The H2 storage of Y(BTC) can reach 1.73wt% at 77 K and 1 atm. At room temperature, the saturated CH4 masses are 97.7 cm3·g-1(STP) at 4 MPa; even under the U.S. DOE pressure standard (3.5 MPa), the masses can reach approximate 96.0 cm3·g-1(STP). This is a very outstanding ability for this kind of porous material. Moreover, Tb, Eu-doped Tbx-Y1-x(BTC)(H2O) or Euy-Y1-y(BTC)(H2O) have eximious optic properties, the cost is reduced deeply as well.
Keywords:metal organic framework  rare earth  hydrogen storage  methane storage  fluorescence
